denon is the deno replacement for
nodemon providing a feature packed, highly configurable
and easy to use experience.
denon does not require any additional changes to your code or method of
development. denon
is a replacement wrapper for deno
. To use denon
,replace
the word deno
on the command line when executing your script.
Features
Denon provides most of the features you would expect of a file watcher and more.
- Automatically restart your deno projects
- Drop-in replacement for
deno
executable - Extensive configuration options with script support
- Configurable file watcher with support for filesystem events and directory
walking - Ignoring specific files or directories with
glob patterns - Not limited to deno projects with a powerful script configuration
Install
To install denon simply enter the following into a terminal:
deno.
1.6.0 to install this executable.
You can upgrade running deno upgrade
.
Usage
denon wraps your application, so you can pass all the arguments you would
normally pass to your app:
denon run app.ts
you can pass arguments to deno:
denon run --allow-env app.ts
and even to your application:
denon run --allow-env app.ts --arg-for-my-app
you can run scripts declared in config:
denon [script name]
and you can see which scripts are available in your config:
to see what else you can do with deno CLI use the help flag:
denon --help
Configuration
denon is designed to be simple but also extremely configurable to fit your
project needs. It supports both json and yaml for the configuration file. The
configuration options in yaml is the same as json making it compatible.
to create a basic configuration in the root directory of your project file you
can run:
denon --init
this will create a basic scripts.
file: json
{ "scripts": { "start": "app.js" } }
you can also initialize from a custom template (see
src/templates.ts
file for all the available templates)
denon --init typescript
JSON config (
scripts.json
template)
Denon configuration can be provided as a JSON file:
{ // optional but highly recommended "$schema": "https://deno.land/x/denon/schema.json", "scripts": { "start": { "cmd": "deno run app.ts", "desc": "run my app.ts file" } } }
JSON Schema
You can use a JSON schema to have type checking on your configuration. Simply
add:
{ "$schema": "https://deno.land/x/denon/schema.json", "scripts": { /* */ } }
YAML Configuration (
scripts.yml
template)
Denon configuration can be provided as a YAML file:
scripts: start: cmd: "deno run app.ts" desc: "run my app.ts file"
Typescript config (
scripts.config.
template)
ts
Denon configuration can be provided as a .config.ts
file:
import type { DenonConfig } from "https://deno.land/x/denon/mod.ts"; const config: DenonConfig = { scripts: { start: { cmd: "deno run app.ts", desc: "run my app.ts file", }, }, }; export default config;
You can use a typescript configuration file to have programmable configuration
based on your environment (for example loading a .env
file):
import { DenonConfig } from "https://deno.land/x/denon/mod.ts"; import { config as env } from "https://deno.land/x/dotenv/mod.ts"; const config: DenonConfig = { scripts: { // same as json configuration start: { cmd: "app.js", desc: "Run my webserver", env: env(), }, }, }; export default config;
Available options
denon takes inspiration from the awesome
velociraptor module in the way it
handles scripts.
Scripts
Scripts are declared inside the scripts
object and are identified by a name:
{ "scripts": { // they all resolve to `deno run app.ts` when you run `denon start` "start": "app.ts", // OR "start": "run app.ts", // OR "start": "deno run app.ts" } }
Scripts can also be defined by a complex object:
{ "scripts": { "start": { "cmd": "deno run app.ts", // with an optional description that // is shown when you run `denon` to list // all the scripts "desc": "Run the main server.", // available options... // they are described in the next paragraph "allow": ["env", "write"], "unstable": true // running `denon start` will resolve in // deno run --allow-env --allow-write --unstable app.ts } } }
Script Options
Options can be script specific or be declared as global in the root of the
config file.
Environment variables
Environment variables can be provided as an object and are passed directly to
the child process.
{ // globally applied to all scripts "env": { "TOKEN": "SUPER SECRET TOKEN" }, "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "env": { "PORT": 3000 } } } }
Permissions
Permission can be granted to child processes. You can provide specific
permissions for each script, but you can also declare permissions globally,
following the same format.
{ // globally applied to all scripts // as object ... "allow": { "read": "/etc,/tmp", // --allow-read=/etc,/tmp "env": true // --allow-env }, // ... or as array "allow": [ "run", // --allow-run "net" // --allow-net ], "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", // specific for a single script // as object ... "allow": { "read": "/etc,/tmp", // --allow-read=/etc,/tmp "env": true // --allow-env }, // ... or as array "allow": [ "run", // --allow-run "net" // --allow-net ] } } }
File watching
While file watching is a core feature of denon
you always have the option of
disabling file watching and run a script only once:
{ // globally applied to all scripts // now denon will essentialy be a script runner "watch": false, "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", // you can still enable watch on a script-by-script basis "watch": true } } }
Import Map
Load import map file. Take a look a at the
official docs
for additional info.
⚠️ This feature in unstable in the current version of the deno executable.
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "importMap": "importmap.json" } } }
TS config
Load tsconfig.json configuration file:
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "tsconfig": "tsconfig.json" } } }
Unstable
Enable if the script is using unstable features of deno stdlib:
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "unstable": true } } }
Inspect and InspectBrk
Activate inspector on host:port
. If
inspectBrk
is used the executions breaks
at the start of the user script:
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "inspect": "127.0.0.1:9229", // OR "inspectBrk": "127.0.0.1:9229" } } }
Lockfile
Check the specified lock file:
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "lock": "lock.json" } } }
Cert
Load certificate authority from PEM encoded file:
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "cert": "cert.pem" } } }
Log
Set log level: (possible values: debug
, info
)
{ "scripts": { "start": { "cmd": "deno run app.ts", "desc": "Run the main server.", "log": "debug" // or "info" } } }
Watcher

Denon: brand information, news, articles, questions • Stereo.ru
Denon (デノン株式会社 denon kabushiki gaisha, “Denon stock company”) is a Japanese consumer electronics company specializing in the production of Hi-Fi and Hi-End audio equipment for professional and home use.
Background
At the beginning of the 20th century, an American expat in Yokohama, Frederick Whitney Horne, who used to import phonographs and wax cylinders, decided to establish his own production. The American-Japanese startup (Japan “nichi” + America “bei”) was originally called Nichibei Chikuonki Seizō Kabushiki Gaisha. New products were promoted by a separate division of the Nichibei Phonograph Company.
As a joint stock company, Nichibei was renamed Nihon Chikuonki Shōkai (Japan Recorders Corporation) and Nipponophone Phonograph Company in 1910 to emphasize the company’s Japanese roots in a country with nationalist and imperialist traditions.
Frederick Whitney Horn
After the rebranding and merger, Horn’s corporate project, Nitchiku, became the first factory in Japanese history with a centralized distribution system for turntables and records, first single-sided, and from 1915 years and double-sided records. Prior to that, all local music was sent to circulation in Europe and the United States.
By 1919, Horn handed over control to his colleague J.R. Gary and left Japan, while Nitchiku continued to absorb local brands: Oriental Phonograph Mfg Co. in 1919, the Standard Gramophone Co. in 1920, Temoku Gramophone Co. in 1921, Sankōd Menophone and Tokyo Record Company in 1923.
Curiously, this essentially American practice eventually led to a decline in the share of Western record labels like Victor, not only in the Japanese market, but also in colonial Korea. And besides, the Japanese government imposed a heavy tax on imported goods, forcing importers to create subsidiaries. Which is what was done.
In the 1920s, acoustic recordings were inferior to the more advanced electrophones, and Nitchiku decided to turn to modern technology. In addition, the surviving early Nitchiku catalogs indicate some connection (at least at the level of licenses) with Columbia.
One way or another, but in 1927 British and American Columbia received 35.7% and 11.7% of the shares of Nitchiku, whose staff headed the combined company Nippon Columbia, and in 1931 she entered the EMI family. However, already at 19In 35, in connection with the political course of Japan towards militarization, Nippon Columbia, along with other companies, was nationalized and transferred to local management.
Brand Genesis
The technical group at Japan Recorders Corporation was called Japan Denki Onkyo (denki for electricity and onkyo for acoustics). It was here that they were engaged in the production of gramophones, and you should not confuse it with the Onkyo hi-fi brand from Osaka – these are completely different people and history. By 1939, Denki Onkyo had been shortened to Denon, and the company had a significant increase in orders.
The state, represented by the national company NHK, was in dire need of broadcasting equipment. In particular, the legendary 78 rpm record of Emperor Hirohito’s surrender was recorded using a model DP-17-K recorder.
Post-war successes
After the end of the war, the professional ties between Nippon Columbia, Denon and NHK did not end – quite the contrary. Collaborative developments in the radio and television industry allowed Denon to subsequently establish itself in the consumer audio market. The first moving coil head appeared in 1951 years old.
DL-103
But perhaps the most famous Denon product in collaboration with NHK – the DL-103 MC cartridge – was released ten years later, and is still produced to this day in various variations, becoming a kind of standard in vinyl sound technology. The development of professional and vinyl equipment has traditionally been handled by the office in Mitaka.
During the 1950s and 1960s, more and more professional and consumer audio equipment, which was entrusted to the second factory in Kawasaki, fell into the field of Denon’s interests – these are reel-to-reel and cassette recorders along with media, radios and even musical instruments. Beyond that, however, NHK and Denon were working on a promising project that would change the face of the audio industry for the future.
Experiments with digital audio recording
NHK, in collaboration with Denon, researched PCM audio coding, for which, on the basis of a VCR, in 1967 they built a mono and in 1969 a stereo model for digital recording with parameters of 13 bit / 47. 25 kHz. The ADC/DAC was Analog Devices’ multi-million yen military radar model.
“The World Of Stomu Yamash’ta”
In 1971, Denon engineer Takeaki Anazawa made the world’s first commercial digital audio recording. These were “The World Of Stomu Yamash’ta” and “Something” (Steve Marcus & Jiro Inagaki), released a year later on LPs made using the master’s straight cut method. Denon representatives claimed that as a result they surpassed the recording quality level of traditional analog tape recorders.
“Something” (Steve Marcus & Jiro Inagaki)
These two editions were recorded in one pass without editing the material, and for real studio work a multi-channel unit was required, which appeared just a year later – in 1972.
DN-023R
In the PCM model The Denon DN-023R had eight channels, and the 47.25 kHz audio was recorded as a low-frequency signal on a 2-inch tape of a four-head Shiba (formerly Hitachi) B&W VCR. It was a cumbersome three-part system—a tape drive, a monitor, and a signal processor—that weighed a total of one ton. On such a device, it was already possible to edit audio material.
The first recording on the new equipment was a performance of Mozart for strings K.458 and K.421 by the quartet im. Sour cream. Later, six more vinyl records were released by Nippon Columbia, recorded using the DN-023R. The recording device itself has also been modified in the direction of reducing the weight and dimensions. The next version of the recorder DN-023RA was already suitable for transportation to field recordings in Europe.
1970s Hi-Fi
In 1977, Billboard magazine presented Denon with the “Trend-Setter Award” for digital sound recording, and PCM soon found its way into the CD market. But in the 70s, Denon not only experimented with new sound formats, but also did not forget about the traditional Hi-Fi market.
DP-5000
Direct drive servo motors in vinyl tables have brought success to the company. So, the 1971 model DP-5000 used speed control using magnetic sensors, providing a detonation level of just 0. 025% inaccessible to traditional belt devices. A similar speed tracking system was used in the DH-710 reel-to-reel tape recorder.
DH-710
The era of the CD
Although Denon, for all its past achievements, was not the founder of the new CD-AudioIntroduced the DN-3000FE large CD player stand for professional use in 1981.
DN-3000FE
And only then, in cooperation with Hitachi, in 1982, offered a consumer top-loading DCD-2000 player. However, subsequent models of Denon players were produced with a traditional horizontal CD tray.
DCD-2000
In the consumer sector, the company also offers its own 20-bit digital filtering algorithms for more accurate processing of CD data. The crowning achievement of this direction was ALPHA technology, which appeared in 1993 in the legendary DA-S1 DAC paired with the top-end DP-S1 transport.
DA-S1 and DP-S1
The DP-S1’s layered body, oil damped copper chassis with air cushion and brass stabiliser, represented the highest form of Denon engineering ambition.
Denon also holds the palm in creating some of the most sonically interesting portable CD players of its time, in particular the Denon DCP-150 with a pair of AD1868 18-bit R-2R DACs.
DCP-150
In the same 1993, digital workstations for working with 20-bit precision appeared in the Denon studio equipment list. The extra four bits were needed to reduce quantization errors when mixing 16-bit digital tracks.
By 1995, Denon’s multi-channel studio equipment had reached 24-bit/96kHz. All this came in handy for new media in 5.1 format.
The DVD era
In the 1990s and early 21st century, Denon focuses on decoding and multi-channel audio media – including music content. Symphony No. 3 “Eroica”, Beethoven’s Egmont Overture and Chopin’s Piano Concerto No. 1 were recorded live in 5.1-channel format at a concert at the Alte Oper in Frankfurt on November 1996 years old
DVD-2000
In 1997, the first DVD-player DVD-2000 appears. The company is equipping a 5. 1 sound recording studio and publishing symphonic music concerts in a new DVD format at its Denon Active Media (DAM) plant in Atlanta.
“Tetsu Takemitsu: Spectrum Canticle (Tatsunori Numajiri & Hibiki Tokyo)”
SACD “Tetsu Takemitsu: Spectrum Canticle (Tatsunori Numajiri & Hibiki Tokyo)” was released in 1999, and in 2001 Denon released its first DVD-Audio – ” R. Strauss: Home Symphony (Inbal & Switzerland)”.
Denon AV processors and AV receivers are among the first to feature the latest decoders for Dolby Digital, DTS and other THX extensions. Also together with Silicon Optix in 2004 Denon presents the Realta HQV (Hollywood Quality Video) video chip in the DVD-A1XV player.
DVD-A1XV
Denon’s migration to the US was not without reason, as the center of the entire film industry is located here. In 2008, the Denon DVD-A1UD became the first all-in-one Blu-ray player to support SACD/DVD-A.
DVD-A1UD
Denon’s most recent achievement to date is the first 13.2 AV receiver, the AVR-X8500H, introduced in 2018 and equipped with everything from Atmos decoders to HEOS branded multi-room.
AVR-X8500H
Finance and reorganization era
In 2001, 98% of Denon’s shares passed from the debt-ridden Nippon Columbia to the American investment holding Ripplewood Holdings, and 2% of the shares remained with Hitachi, which no longer had the ability to operationally manage affairs. The amount of the transaction between Ripplewood and Nippon Columbia was 49million dollars. At the same time, at the time of the sale, Denon had assets worth 186 million and a debt of 82 million.
In 2002, the Denon brand, along with Marantz, was moved into the new D+M holding, which then included other hi-fi names such as Boston Acoustics and McIntosh. Ripplewood owned 68.6% of D+M shares, while Philips, the previous owner of Marantz, held 14.7%.
Denon Professional, Marantz Professional and Denon DJ were spun off and sold from D&M in 2014. The buyer was Florida-based inMusic, which also owns Numark, Akai and Alesis. In 2017, the D + M holding was sold to the American concern Sound United, whose portfolio already included acoustic brands Polk Audio and Definitive Technology. The terms of the deal were not disclosed.
Denon’s history – 110 years of innovation
Denon 110 Year Anniversary – SPIRIT OF INNOVATION
First Denon logo, late 1930 a long time for the world of home audio, taking us back to the very first the days of the creation of musical devices and the appearance of the first gramophones and records. All along, Denon has always had the same intent – to provide our customers with access to the exciting world of music, great musicians and cinema-quality sound right in their homes.
Frederick Whitney Horn
Founded by American entrepreneur Frederick Whitney Horn with Japanese partners, Nippon Denki Onkyō Kabushikigaisha (literally translated as “Japanese Electric Sound Company”) was founded in 1910 as part of the Nippon Chikuonki Shokai (Japan Sound Corporation). pissing devices).
Nippon Chikuonki Shokai Factory circa 1910
At that time, the parent company produced single-sided discs, which until then were mainly used for voice recording and gramophones. This was only a few decades after Edison first invented his phonograph, which recorded sound on a wax cylinder, and Emil Berliner had only recently made the transition from cylinders to discs, on which we still listen to music today. In America, customers at this time were still listening to the cylindrical record player – the phonograph that Edison had invented!
Disk recorder production
The new manufacturer was not only the first consumer audio company to sell gramophones, but also the first record company in Japan. This illustrates where the name Denon came from in 1930, from the first syllables of the words Denki and Onkyo. The company has always been at the forefront of ‘electric sound’, and has not only produced equipment designed to reproduce music, but also recorded music itself.
Nipponophone No.35
AT THE ORIGINS OF REVOLUTIONS
Denon pioneered many revolutions in home audio, releasing the first LP records, developing new digital technologies for the first CDs back in the early 1970s, and releasing the first the world’s line of AV receivers over 30 years ago.
With the release of the 110 Anniversary Series, Denon not only celebrates a milestone in the company’s history, but also celebrates 110 years of great sound that Denon engineers have brought to life in the Anniversary line, from the AVC-A110 13.2-channel AV receiver to a special version of the legendary DL-A110 pickup.
MILESTONES IN HISTORY
From the very beginning, Denon has been committed to the development of the entire sound recording and playback chain. Just two years after its founding, in 1912, the company merged with Japan-US Recorders Manufacturing, the first of a series of mergers. In 1928 the company became part of the world famous record label Columbia Records and was renamed Japan Columbia Recorders. And in 1946, the company was renamed Nippon Columbia and at that time cooperation began with the national broadcasting company of Japan – NHK.
Denon DP-17K Vinyl Recorder
It was for broadcasters that Denon launched its first professional recorder, a two-deck portable recorder called the DR-148. Through the use of acetate recording discs, the recorder had immediate playback capability and NHK planned to use it for the 1940 Tokyo Olympics. By this time, the company already had a special plant for the production of recorders, developed a sapphire cartridge for playing acetate discs, and a low-vibration synchronous motor.
In 1944, the company officially became Japan Denki Onkyo Co., Ltd., and its Denon DP-17K recording machine was used to record Emperor Hirohito’s speech at the end of World War II. This was the first time the Japanese public had heard the Emperor’s voice, but it took two takes before the speech was ready for transmission: to the dismay of NHK technicians, the first time the Emperor spoke too quietly.
IN THE ERA OF TAPE AND LP
In 1948, a revolution occurred in the audio recording market – the then largest record company Columbia first released the so-called Long Play Record (LP), designed for a speed of 33⅓ rpm and at the same time appeared on the market a completely new type of sound recording – recording on magnetic tape.
Denon keeps up with the times with the introduction of its first portable tape recorder – much more reportable than disc recorders, which were “portable” at best. The R-28-F tape recorder was adopted by NHK and by the late 1950s, the Mitaka plant, originally intended for the production of disk recorders, was almost completely switched to the production of tape recorders, which was accelerated by the advent of stereo recordings and stereo players in the 1958 year. Production of disc recorders ceased entirely in 1963. Still primarily targeting professional users, Denon released its first SH-31 headphones in 1966.
The Denon DN-302F was the first direct drive turntable for broadcast studios.
In 1964, together with NHK, the company introduced the DL-103 cartridge. It went on to become one of the legendary Hi-Fi products of all time, popular with broadcast studios and home audio enthusiasts alike. It is still produced at the Denon Shirakawa factory in Japan, more than 55 years after its introduction, and its technology and high sound quality are at the heart of the special cartridge in the 110 Anniversary line, the DL-A110. At 19In 1970, the company introduced its first direct drive turntable, the DN-302F, for broadcast studios. This year also marked another important milestone – for the first time the Denon name began to appear on products aimed at the mass consumer, and one of the first products was the legendary DP-5000 direct drive motor unit for turntables, to which the buyer could add his plinth , tonearm and cartridge. Two years later, the best-selling model DP-3000 came out, and in 1976 – top model DP-7000 with direct drive and quartz stabilization. These Denon direct drive turntables continue to be highly sought after by vinyl enthusiasts for their great sound and high reliability.

DIGITAL AUDIO ERA
World’s First Denon Digital PCM Recorder DN-023R
B 1972 Denon releases its first integrated stereo amplifier Denon PMA-500, but Something even more important happened behind the scenes of the professional audio world when the Denon DN-023R, the world’s first digital PCM recorder designed by Denon, was announced. The eight-track device has been received with interest by the broadcasting industry. Denon also pioneered the development of the world’s first professional CD player. DN-3000F. Launched at 19At 81, it was a year ahead of the consumer debut of CD players. The DN-3000F has been designed for studio use, with the advanced search capabilities and instant start needed for on-air work.
Denon’s first consumer CD player DCD-2000
Denon’s first consumer CD player, the DCD-2000, was followed just a year later by the DCD-1800 using Super Linear Converter technology. These products were also produced at Shirakawa Audio Works, north of Tokyo, where many of Denon’s models are now made, including the Anniversary 110 Series, which is the crowning achievement of Denon’s engineering expertise and craftsmanship.

INVENTION OF HOME CINEMA
The Denon AVC-2000 is one of the first AV receivers with Dolby Pro-Logic Surround sound.
Until 1985, Denon’s focus was on recording and playing music in stereo, but that changed with the introduction of its first AV amplifier, the AVC-500. At the time, the market was unchallenged by VHS tapes with stereo sound, but the AVC-500 had what has been called a “surround sound feature to add atmosphere to stereo”. Denon Surround was a full surround sound system using the rear channels via an additional amplifier with a 30ms time delay applied to the rear channels to create surround and feel like you are in a hall or theatre,
Yes, it seems like a very simple solution compared to today’s AV receivers and amplifiers, with their many features, multi-channel audio processing, 8K video support, and even network capabilities, but the AVC-500 was the first, and it was another revolution in the world of audio. Just three years later, the AVC-2000 with Dolby Pro-Logic Surround sound was released, followed three years later by Denon’s legendary surround sound combo of the AVP-5000 processor and the POA-5000 multi-channel power amplifier.
In the meantime, the company continued to develop and improve equipment for the professional market and in 1990 the company released the first Digital Audio Tape (DAT) player, the DTR-2000G. The 1990s also saw the introduction of some models that were destined to be the forerunners of classic Denon hi-fi components for several decades, such as the 1991 Presta series of mini components that formed the basis of all mini systems up to the D-M.

A STEP INTO THE FUTURE WITH NEW TECHNOLOGIES
Just as these first home theater products and mini systems set the style for Denon’s future models, the introduction of the flagship S1 series in 1993 introduced a large number of technologies that are still used in company models. Models in the S1 range (the S stands for sensitive) included the DP-S1 CD transport and the DA-S1 external D/A converter with Denon Alpha Processing technology, designed to reproduce more analog sound than conventional digital sources. Amplification was provided by a PRA-S1 preamplifier and two POA-S1 monoblocks.

Denon’s amplification technology was called UHC- (Ultra High Current) Single-Push-Pull-Circuit allowed to combine high power output with precise musical expression. It was a top class solution, the first of its kind. The technology made it possible to reproduce not only high dynamics, but the smallest nuances of sound that convey the emotions of the performers. Also for the first time, Direct Mechanical Ground Construction technology has been applied, which eliminates cabinet vibrations and provides a cleaner sound. New technologies and solutions of the S1 series also touched upon the DL-S1 pickup and the associated AU-S1 phono stage.

INCREDIBLE EXPERIENCE
Based on new technologies, Denon engineers have expanded and improved the capabilities of home audio components. In 1997, Denon introduced the world’s first five-channel surround sound system, and just a couple of years later, Denon launched the AVC-A10SE, the first multi-channel amplifier to support THX Surround EX technology. It was followed by the world’s first AV receiver to support DTS-ES Discrete 6.1, the AVC-A1SE.

Finally, 2008 saw the arrival of the Denon AVP-A1HD ultra-high-end AV processor and Denon POA-A1HD power amplifier without compromise. – this time offering already ten channels of amplification and an absolute level of sound quality.

The next breakthrough came with the move to Blu-ray discs, which offered even higher sound and picture quality. In 2009, the DVD-A1UD was released, the world’s first “universal” disc player that supports BD, SACD, DVD and CD. Played all possible sound formats on all possible disc formats!
Today, Denon continues to innovate in products for home users. Drawing on over a century of audio engineering experience, Denon’s latest products now support high-resolution audio streaming as well as all possible surround sound formats such as Dolby Atmos, DTS:X and Auro 3D. All of them are designed to immerse listeners in the world of their favorite music and films. Modern Denon AV receivers offer up to 15 channels of surround sound and 8K video. Get ready for the next generation of home entertainment.
